To illustrate the imaging signs of intraarticular osteoid osteoma (OO) of the hip in 13 patients followed in our center. To demonstrate the imaging usefulness,
in the diagnosis of this entity. Normal 0 false false false PT JA X-NONE To point out the main differences between the most common form of cortical OO and intraarticular OO.
Normal 0 false false false PT JA X-NONE Osteoid osteoma (OO) is a benign bone lesion,
representing almost 10% of all benign skeletal lesions (1).
It is most frequently seen in young patients in their 20s and 30s,
with a peak age in the early twenties (1,2).
A male predominance has already been established,
with a reported male-to-female ratio of 4:1 in one large patient series (3). Normal 0 false false false PT JA X-NONE OOs can involve any bone of the skeletal system,
but is mostly reported...
Imaging findings OR Procedure Details
We retrospectively collected from 2010 until 2015,
25 cases of OO,
13 of them were intra or juxta articular hip OOs (table1).
The much higher percentage of intra or juxta-articular hip OOs depicted in this series,
when comparing with published radiological series,
was due to the fact that our hospital is a reference centre on hip surgery.
We have made the correlation between the radiological findings and the histology after surgery to validate the imaging diagnosis. The most affected joint in...
particularly on the hip are problematic lesions both in terms of being more difficult to detect and in terms of having a nonspecific appearance on imaging. Normal 0 false false false PT JA X-NONE Normal 0 false false false PT JA X-NONE
